Hi Rien,
Oops,
I didn't realise this was a long running topic and more or less repeated myself *eek*

The 356 is the quietest running cam in my opinion, the larger clearances used with the 334 add noise in my experiences.

Some time ago a friend fitted a 334 to his A10,
I know it had some other problems but it sounded horrible with the 334. It soon got changed back to a 356 that it originally had.
The 334 went into an Ariel Huntmaster  (54) and this sounded rattly with 10 and 15? thou clearances,

Thanks RR. We've checked the cam followers and they came onto the camshaft.

Update: so now I have a camshaft 0334 and I've made a solid copper head gasked of 2.0mm installed. The noise is over!  Thanks everyone for the comments.
did you manage to source a new one? and if so from where?

Did not found a new 334. It's an old one but better than mine.
